Accepted Answer

Question 8

Accepted Answer

A) True 
 B)False

Question 9

Researchers are concerned with sample size because a significant cost savings occurs when the correct sample size is calculated and used.

Accepted Answer

A) True 
 B)False

Question 10

Arbitrary sample size approaches rely on erroneous rules of thumb.

Accepted Answer

A) True 
 B)False

Question 11

The conventional sample size approach ignores the circumstances surrounding the study at hand and may well prove to be much more costly than would be the case if the sample size were determined correctly.

Accepted Answer

A) True 
 B)False

Question 12

________ pertains to all sources of error other than the sample selection method and sample size,including problem specification mistakes,question bias,data recording errors,or incorrect analysis.

Accepted Answer

A) Nonsampling error 
B) Sample bias 
C) Survey bias 
D) Sampling error 
A) Nonsampling error 
B) Sample bias 
C) Survey bias 
D) Sampling error

Question 13

Sometimes a research objective is to perform subgroup analysis,which has direct implications:

Accepted Answer

A) On statistical analysis techniques. 
B) For sample size. 
C) For survey cost. 
D) For survey completion time. 
A) On statistical analysis techniques. 
B) For sample size. 
C) For survey cost. 
D) For survey completion time.

Question 14

A lower sample size means less effort,time,and cost,so there are good reasons for a researcher to try to estimate p rather than to take the worst case.

Accepted Answer

A) True 
 B)False

Question 15

Focus on budget factors usually ignores the value of the survey's results to management and does not consider sample accuracy at all.

Accepted Answer

A) True 
 B)False

Question 16

As a general rule,a small population situation is one in which the sample exceeds 15% of the total population size.

Accepted Answer

A) True 
 B)False

Question 17

On occasion,a research objective is to perform subgroup analysis,which is an investigation of subsegments within the population.The effort to gain knowledge about subgroups has direct implications for sample size.

Accepted Answer

A) True 
 B)False

Question 18

When applying the standard sample size formula using percentages,there are two alternatives: (1)expect the worst case or(2)guesstimate the actual variability.

Accepted Answer

A) True 
 B)False

Question 19

Sample sizes based on statistical analysis criteria can be quite small.

Accepted Answer

A) True 
 B)False

Accepted Answer

A) A census is the only perfectly accurate sample. 
B) A probability sample will always have some inaccuracy(sample error). 
C) A probability sample size can be a very tiny percentage of the population size and still be very accurate.
